RUFFLING ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 333,516, dated January 5, 1886, Application filed January 2, 1885. Serial No. 151,886. No model.)

To all whom it may concern,-

Be it known that I, HARRY O. GOODRIOH, residing at Chicago, in the county of Cook and State of Illinois, and a citizen of the United Stateshave invented new and useful Improvements in Ruffiing Attachments for Sewing-Machines, of which the following is a full description, reference being had to the accompanying drawings, in which Figure l is a side elevation; Fig. 2, a bottom view of a portion of the presser-foot; Fig. 3, an enlarged detail, being a vertical longitudinal section through the presser-foot; Figs. 4 and 5, details, being a side elevation and bottom View, respectively, of a presser-foot, showing an immovable bearingpoint for the ruffling-blade.

This invention relates to means for increasing or decreasing the pressure of a compensating head or block upon the material passing beneath a ruffling attachment to be gathered by a rufflng-blade, and to rocking or turn ing the ruffling-blade to correspond in position to the position of the compensating head or plate.

The invention will be hereinafter specifically described, and pointed out in the claims.

In the drawings, A represents a presser-foot having, as shown, atits heel end a socket, A, for attachment to the pres'ser-bar of a sewingmachine, and at its forward end an arm, A, from which the rufflingblade is suspended. The presser-foot proper, A, is provided with a needle-hole, a, and the socket portion at the rear edge is provided with a recess, a, to receive an arm carrying a' separating-blade, (not shown,) and the side of the presser-foot at the toe end is provided with slots a, for the passage and guidance of overlay-strips when used.

B is a compensating head or plate having its forward edge beveled to form a biting-edge, b, in line with the center of a hole, a which, when the parts are together, coincides with the hole a. This plate is pivotally mounted on the end of a spring or spring-arm, b, attached to the under side of the heel portion of the presser-foot by a screw or pin, b", and this compensating head and spring or springarm as a device are made the subject-matter of a separate application filed herewith, Serial No. 151,885.

Passing through the presser-foot A is a screw, b, the end of which comes in contact with the spring or spring-arm b, furnishing a fulcrum against the spring or spring-arm, by which the head or block can be made to occupy a hlgher or lower plane as carried by the spring or spring-arm, so as to'press on the material operated on with the proper degree of pressure. The end of the screw engages the spring between the attached end and the head or block, and its position relative to the head or block can be changed,- so as to length-' en or shorten the distance between the end of the screw and the head or block, and thereby lengthen or shorten the spring, and, as shown, the end of the screw bears on the spring about midway between the block B and the screw 0. Its position, however, can be changed forward or back of this point. This screw can be turned down, projecting its bearing end-and throwing down'the spring, and at the same time shortening the length of spring, so that the block will lie in a lower plane and the pressure of the spring will be increased, or it can be turned up to allow, the block to lie in a higher plane with an increased length of spring, decreasing the amount of pressure.

0 is a rufliing-blade carried by an arm, 0,

which, as shown, projects out from a pendant D, the upper end of which has which are adj usting-screws d and d, for regulating the movement of the blade.

E is a lever havinga slot, E, for attachment to the needle bar. This lever E has two points at its pivoted end, one of which only, e, is shown, by which the arm or pendant I) is swung back and forth to reciprocate the fold ing-blade. As shown, a guide-bar. c, is attached to the bar 0 by a socket, c, to form a guide-passage, a", for the strip to be ruffled.

The parts represented by the letters 0, D, D, E, c, c, c, d, d, and e form no part of thls lnventlon, and are only represented to show one well-known form of ruffling attachment. The block B can turn endwise to form a bearing-surface the entire width of the foot, and thereby take up any irregularity in feed between the face of the feed-dog of the machine and the presser-foot, and in order to facilitate the turning of the acting end of the ruffiing-blade to conform in position to the posia head, D, in

tion of the head or plate,this blade comes in contact with a bearing-point, b, which point, as shownin Fig. 3, is made adjustable by having a screw-thread thereon, by which it can be made to proj ectagreater or less degree, and,as shown in Fig. 4, is stationary, being cast or formed with,or otherwise suitably secured to, the under face of the toe end of the presser-foot. This bearing-point forms a fulcrum, against which the ruffling-blade will bear, holding the blade, to a slight extent, from the under face of the presser-foot, and snfficiently far for the acting end to turn or twist to pass beneath the compensating head or plate, producing a torsional movement of the blade to correspond with the feed-surface of the sewingmachine, and this bearing-point can be used irrespective of the compensating head or block and adjusting-screw therefor.

V I do not herein broadly claim the combination, with a non-rocking presser-foot, of a rocking blO(k or plate pivotally connected therewith, as such constitutes the subject matter of my application filed May 19, 1885, Serial No. 166,021; nor do I broadly claim herein, in a sewing-machine ruffler having a reciprocating ruffling-blade, a foot part having a transverse recess in its sole, and provided with a supplemental presser foot or sole-piece within said recess, and with a spring orsprings adapting the latter to press independently upon the crimps or gathers as they are successively completed and left heneath it, as such is embraced in my application filed December 29, 1884. Serial No. 151. 882; nor do I herein broadly claim, in a sewingmachine rufder having a reciprocating ruffling-blade, a foot part constructed with a pressing surface which rests upon the sewed ruffles or gathers behind that point at which the crimps or gathers are successively completed or finished, and provided at the point last named with a supplementary presser part or sole-piece free to rise and fall independently of the pressing-surface, as such is embraced in my aforesaid application, No.

151,882; nor do I claim herein the combination, with a recessed presser-foot and a rufand the top of fling-blade, of a compensating block or plate arranged at the under side of the presser-foot, and a torsion-spring carrying the block and permitting it to rise and fall and twist itself as required, for bearing-purposes, as such is embraced in my aforesaid application, No. 151,882; nor do I herein claim the combination of a non-rocking presser-foot having a recess on its under side and a block rocking endwise on a bearing-point and located in the recess with 'a reciprocating ruffling-blade, as such is embraced in my application filed December 29, 1884:, Serial No. 151,881; and, finally, I do not herein claim, in a sewing-machine rufiler having a reciprocating rufliing-blade, a foot part constructed with a pressing-surface which rests upon the sewed ruflle or gather behind the point at which the crimps or gathers are successively completed or finished, and pro.-

vided with a supplemental p-resser part or Y sole-piece, which rests upon the crimps or gathers at said point where they are completed or finished, and with an independent presser spring or springs between the latter said foot part, as such is embraced in my applicationfiled December 29, 1884, Serial No. 151.88i. I

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a resser-foot formed with a recess in its under side, and a reciprocating ruffling-blade, O, of a head or block, B, in the recess, a spring to which the head or block is secured, and by which it is carried to rise and fall, and a set-screw for projecting the head or block more or less from the recess in the presser-foot, substantially as described.

2. A presser'foot, A, having a projecting bearing-point, I), in combination with a ruffiingblade operating beneath the presser foot for givingatorsional movement to the 9c blade, substantially as and for the purpose specified.
